IMPROVEMENT IN HEATING-'STOVES.

Specification forming part of Letters Patent No. 129,315, dated July 16, 1872.

To whom it may concern.'

Be it'known that I, JOHN V. B. CARTER, of Detroit, in the county of Vayne and State ot Michigan, have invented a new and useful Improvement in Heating-Stoves; and I do declare that the following isa true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1 is a transverse vertical section on the line w a* in Figs. 3, 4, and 5. Fig. 2 is a cross-section on y y, Fig. 4. Fig. 3 is a plan of the top, the cap being removed. Fig. 4 is a horizontal section on thc plane z z in Fig. 2. Fig. 5 is an inverted plan ofthe base, the bottom-plate being removed. Fig. Gis a perspective view of the draught-register case from the inner side. Fig; 7 is a cross-section of the same, and Fig. 8 is a detached perspective view ot' the battle-plate detached.

Similar letters of reference kindicate correspondin g parts in the several figures.

The nature of this invention relates to certain improvements in the construction of woodburning heating-stoves, whereby the heated currents are reverted through a short internal diving-flue into a doublebase,whence they rise, after being therein divided, through a ide single iiue at the front of the stove into a double top before passing out into the smokepipe, while the stove is so arranged as to have a direct draught at will. It also relates to a peculiar draught-register case provided with a partial diaphragm perforated to serve asa baffle-plate, the object of which is to prevent sparks from being thrown out through the register, and to increase the draught at the lower part of the incandescent fuel.

The invention consists in the peculiar construction and arrangement within the oval sheet-m etal shell and with relation to a doubletop and base, as described in the Letters Patent of John D. Miller, assignor to the Detroit stove-works, dated October 3, 1871, and numbered 119,634, of the descending-due at the back ofthe stove, a dividing-strip in the base and a risin g-ilue at the front of the stove 5 also, in a peculiar case for conveying the draught from the register to the interior of the stove, and provided with a bathe-plate in the upper half of its middle section to prevent sparks or coals from being thrown out into the apartment. 4'

In the drawing, A represents the base of my stove mounted on suitable legs. B is an ova-l sheet-metal shell mounted thereon, and on it is erected a double top, composed of the plates C and C joined at their peripheries. Through the center of the double top is a'feed-chute, D, and at the back part of the cap is an outlet, E, surrounded with a collar to receive the smoke-pipe. F is a damper closing an opening in the inner top-plate operated by a rod, F, by which it may be swung up against the chute, and thus give a direct draught. G is the bottom-plate of the stove, forming, with the base-plate, a bottom or base-chamber.

All the foregoing parts being substantially the same as the corresponding ones shown in the above-mentioned Letters Patent, their invention is hereby disclaimed.

H is the diving-flue plate about one-half the height of the combustioichamber, straight, and forms a chord of theellipse of the stove provided with a grating at the top to prevent coals or fuel from falling into the base-chamber, which it communicates with through an openin g in the base-plate. I is a dividing-plate in the base-chamber in the direction of its transverse axis, leaving a passage-way at each end. J is the up or return iiueplate, being a straight plate, forming a chord at the front part -of the shell, extending from the base chamber to the top-chamber, through suitable openings in their plates. K K are segmental castings, preferably corrugated, extending from the edges of the diving-due plate to those of the return-flue plate, and form the lining ot' the stove.4 Bf is a door at one end of the stove for the introduction of fuel. lf the damper F be closed, the heated currents will pass down the back-flue into the base-chamber, where they will be divided by and pass around the ends of the strip I, whence they will pass to the front flue and rise up into the double top, passing around the chute, and finally make an exit into the smoke-pipe.

It will be noticed that the heated currents are causedto pass in contact with the exterior walls of the stove at every change of direction, and thus give up a large proportion every square inch of the exterior surfaces-of the stove is available for direct radiation, making this stove a powerful but economical heater.

As is well-known, wood-burning stoves are open to the objection of throwing out live coals and sparks through the draughtregister, to the great danger of the carpet and door ofthe apartment, and also to the fact that ashes fall out through the draught-opening. To overcome these objections I construct my draughtregister case as shown, `and which I will now describe. L is a case cast with a rectangular flange, a, at the inner end, with a hole drilled at each corner. From this flange the top part extends horizontally forward to a front wall, b, but na-rrowin g as it approaches it. The sides c c are vertical and follow the outline ot' the top, but the bottom curves upward to a flange or collar, d, in the front wall, which protrudes through an opening in the shell of the stove, where it has secured to it a register to admit the. draught ot' air. M is a rectangular perforated baftle-plate provided with the angular lug e at each upper corner, by means of which it is secured and suspended within the'upper halt ot' the case, by the same bolts or rivets which secure the latter to the front-due plate,

so that sparks snapping out will be arrested bysaid plate, as also the ashes, when the chamber is lled. The draught entering through the register sweeps down under the batiep1ate,`which contracts the area of opening sufficiently to give it force, and impinges upon the lower part of the incandescent fuel, where it is most needed. Should `the stove get too full of ashes and they thus stop the draught-way under the plate there would be still suicient area ot' draught-opening through the apertures inthe baffle-plate to support combustion.

What I claim as my invention, and desire'to secure by Letters Patent, is

The construction and arrangement, with relation to the shell B, base and bottom plates A G and top-plates C C', of the diving-liuc plate H, dividing-strip I, and return-flue plate J, these parts being combined with the draughtregister case L, constructed substantially as described, and provided with the ba-ile-plate M, or its equivalent, for the purpose specified.
